BED-SPRING.

Specification of Letters Patent.

Patented Dec. 17, 1907.

Application filed February 7. 1907. Serial No. 356,261.

To; cZLiflwm it may concern:

Be it known that I, WILLIAM RAPHAEL Bql'syan'r, a subject of the King of'Great Britain, residing at St. David de Levis,

-' clear, and exact descri tion of the invention,

such as will enable ot ers skilled in the art to which it appertains to make and use the same.

Y My invention relates to bed springs; theinvention is to rovide a bed sioned, loosened, or removed independently of the other springs forming part of the set of springs, so that the whole set may be packed m a small space; a further'object is to provide means for adjustablyi attaching the spring to an ordinaryform of bed frame; and, my inventionconsists of theconstruction, combination and arrangement Y of parts, as herein illustrated, described and vation of a single spring,

claimed. v

In the accom anying drawings, forming part of this app 'cation, I have illustrated one form of embodiment of my invention, in whichtdrawings similar reference characters desi ate corresponding parts, and in which: Figure 1 is a plan View; Fi 2 is a side ele- .i .3 is an enlarged side elevation ofa sing e spring;vFig..

' 4; is a plan view.

Referring to the drawings, :1 designates a broad flat spring, which is slightlycrimped or-corrugated to increase itselasticity, and

which has formed on its. ends hooks 2."

' Removably attached to the hook 2 adjacent the foot end member Gof the bed frame, is a hook 3, adapted to fit over the usual angle iron frame C.

Disposedv transversely of the side frame members A, and parallel to and adjacent the head frame member B of the bed, is a bar 5, to which is securedthe ends of yokes 6, which yokes are adapted to be engaged by the hooks 2 formed onthe springs 1.

Hooked members 7 are provided with the screw-threaded body 8, which is disposed through the bar 5 and ad'ustably maintainedtthereon by means of t e nuts 9. The hooked, members 7 are disposed over the head bed frame member B, so that the bar 5 may be. adjusted towards or away from the frame to increaseor decrease the tension on the springs 1.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

A bed spring comprising a flat corrugated body, hooks integrally formed on the opposite ends thereof connections between the hooks on one end'of the spring and the framework of the bedstead, a spring loop removably secured to the other of said hooks, an adjusting bar, resilient arms extending from said loop and engaging said bar, and means for adjustably connecting said bar to the framework of a bedstead.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
